    (54) Image processor for detecting incomplete articles


    (57) In an image processor for detecting incomplete articles according to the present invention, the image of a complete article is produced by means of a television camera (17a, 17b, 17c, 17d) so as to record the image, and the operator designates an area of the complete article that is considered to be essential in judging whether or not the subject of the inspection is complete while observing the reproduced image. Following this, the image of an inspection article is produced by means of another television camera (27a, 27b, 27c, 27d). The video signals are binarized, and the number of the picture elements of the inspection article within the designated area is then counted. The inspection article is judged as being incomplete when this counted value fails to conform to the reference value obtained by statistically processing the number of the picture elements of the complete article.
